Protein Modification Reagents

Chemical agents used to modify the amino acid side chains of proteins in order to alter their native charges, block or expose reactive binding sites, inactivate functional groups, and change functional groups to create targets for crosslinking and labeling.

Advanced Biomatrix Extralink PEGDA Thiol-reactive crosslinker for HyStem-C and HyStem-HP, 10 units x 0.5 mL

Extralink PEGDA is a thiol-reactive crosslinker designed for use in HyStem-C and HyStem-HP kits. Pack comes with Buffer B. HyStem V2.0 kit components are reconstituted with a buffered 1X PBS. The resulting components will also result in a pH neutral isotonic salt hydrogel. The ending pH, osmo, and rheological properties are the same from Version 1.0 to Version 2.0. Extralink is polyethylene diacrylate (PEGDA) with a molecular weight of 3500 Da. It is a thiol-reactive crosslinker that covalently reacts with the thiol groups in Glycosil, Heprasil and Gelin-S to form viscoelastic hydrogels. Extralink vials are >80% acrylated and supplied as the crosslinking component in all HyStem hydrogel kits. Extralink vials are paired with HyStem-C and HyStem–HP kits while Extralink-Lite vials are paired with HyStem hydrogel kits to provide comparable experiences despite the different HA concentrations.

Ubpbio TCEP Powder, 10 GR, CAS# 51805-45-9

Reducing Agents - TCEP - TCEP (tris(2-carboxyethyl)phosphine) is a strong reducing agent. Compared to dithiothreitol (DTT) and β-mercaptoethanol, TCEP has the advantages of being odorless, a more powerful reducing agent, an irreversible reducing agent, more hydrophilic, and more resistant to oxidation in air. It is soluble in water and stable at neutral pH. It does not reduce metals used in immobilized metal affinity chromatography such as Ni-NTA resin. TCEP is particularly useful when labeling cysteine residues with maleimides.
